| Zusammenfassung: | PROBLEM TO BE SOLVED: To improve the transmission efficiency of an entire system.SOLUTION: A terminal device includes: a control unit that sets one or more second TTI settings according to control information from a base station device; and a reception unit that, when the second TTI settings are set, monitors a first PDCCH corresponding to a first TTI and a second PDCCH corresponding to a second TTI shorter than the first TTI, and receives a second PDSCH mapped to the second TTI, and that, when the second TTI settings are not set, monitors the first PDCCH and receives a first PDSCH mapped to the first TTI.SELECTED DRAWING: Figure 17
【課題】システム全体の伝送効率を向上させる。【解決手段】端末装置は、前記基地局装置からの制御情報により１つ以上の第２のＴＴＩ設定を設定する制御部と、前記第２のＴＴＩ設定が設定される場合、第１のＴＴＩに対応する第１のＰＤＣＣＨと、前記第１のＴＴＩよりも短い時間長の第２のＴＴＩに対応する第２のＰＤＣＣＨとをモニタリングし、前記第２のＴＴＩにマッピングされる第２のＰＤＳＣＨを受信し、前記第２のＴＴＩ設定が設定されない場合、前記第１のＰＤＣＣＨをモニタリングし、前記第１のＴＴＩにマッピングされる第１のＰＤＳＣＨを受信する受信部とを備える。【選択図】図１７ |
